Seaview Outfall

Planning how we will continue to manage temporary discharges of treated wastewater, to protect our people and the environment.

The existing resource consents for temporary discharges of treated wastewater from the Seaview Wastewater Treatment Plant to the Waiwhetu Stream will be expiring on 1 February 2018. New consent applications will need to be lodged by 1 November 2017.

New resource consents and consultation

Before any new resource consent applications are lodged, we need to look at the possible options for the temporary discharges of the treated wastewater. This will include the existing arrangement as well as other options. We’ll be talking to the community and stakeholders about these options and will be seeking their input. Their feedback will form part of the consent application.

Background

There are two consents expiring on 1 February 2018:

Consent to temporarily discharge treated wastewater to the Waiwhetu Stream during and/or immediately after heavy rain events when flows exceed the capacity of the main outfall pipeline and the storm tank system is fully utilised.

Consent to temporarily discharge treated wastewater when the main outfall pipeline is being repaired.
